Iko Kushandiswa kweSodium Cyanide muIndasitiri yeElectroplating

Kuisa simbi mumagetsi (electroplating) inzira yakakosha muindasitiri yekugadzira zvinhu, inosanganisira kuisa simbi yakatetepa pamusoro pechinhu chesimbi kuburikidza neelectrolysis. Maitiro aya haangobatsiri chete kuti simbi isarambe ichiora asi anovandudzawo runako rwayo uye kunaka kwayo pamusoro. Sodium cyanide , chinhu chine chepfu yakawanda asi chinoshanda zvakasiyana-siyana, chinoita basa guru muindasitiri yeElectroplating.

Izvo zvakakosha zveElectroplating

Electroplating yakavakirwa pamusimboti we electrolysis. Mune electroplating setup, iyo simbi workpiece inofanira kuiswa inoitwa cathode, nepo simbi ichaiswa inoshandiswa seanode. Ose ari maviri cathode uye anode anonyudzwa mumushonga we electrolyte une maion esimbi esimbi yekuputira. Kana magetsi achipfuura nepakati pe electrolyte, ioni dzesimbi mumhinduro dzinokwezvwa kune cathode (iyo workpiece) uye inoiswa pamusoro payo, ichiita mutete, yunifomu yesimbi yeplating.

Basa reSodium Cyanide mu Electroplating

Sodium cyanide (NaCN) inoshandiswa zvakanyanya mu electroplating seComplexing Agent . Inokwanisa kugadzira stable complexes ine ma ions akasiyana-siyana esimbi. Panyaya ye electroplating, aya ma complexes esimbi-cyanide ane zvakanakira zvakawanda:

1. Hunhu Hwakawedzerwa hweKuputira : Macomplex esimbi-cyanide akaumbwa neSodium Cyanide anobatsira mukuwana kuiswa kwesimbi kwakafanana uye kwakapfava pamusoro pebasa. Semuenzaniso, mukugadzira electroplating yemhangura, copper-cyanide complex inoita kuti maion emhangura agare zvakaenzana, zvichikonzera kuti copper layer ive yakakora uye inonamatira. Izvi zvakakosha pamashandisirwo apo kusimba kweplate layer kwakakosha, senge muindasitiri yemagetsi yekubatanidza maplate.

2. Kufukidzwa Kwakavandudzwa : Kushandiswa kwe sodium cyanide mumushonga we electrolyte kunovandudza simba rekukanda mubhavhu rekuputira. Simba rekukanda rinoreva kugona kwemushonga wekuputira kuisa simbi yakafanana pachigadziko chebasa, kunyangwe pazvikamu zvakaoma zvine mipendero nezvinobuda. Macomplex esimbi-cyanide anogona kusvika zvinobudirira pazvikamu zvese zvechigadziko chebasa, zvichiita kuti chifukidzwe zvakakwana. Izvi zvinobatsira zvikuru mumaindasitiri akaita semotokari, uko zvikamu zvine geometries yakaoma zvinoda kuputirwa kuti zvidzivirire ngura.

3. Stable Plating Bath : Sodium cyanide inobatsira kuchengetedza kugadzikana kwe electroplating bath. Inodzora huwandu hwema free metal ions mumushonga, ichidzivirira kuumbwa kwesimbi dzisina kunamira zvakanaka kana dzisina kunaka. Nekugadzira stable complexes, inobvumira maitiro e electroplating akadzorwa uye anowirirana.

Yakananga Mashandisirwo eSodium Cyanide muElectroplating

1. Kuisa Copper Plating : Mukuisa copper electroplating, Sodium cyanide inoshandiswa kugadzira copper-cyanide complexes. Izvi zvinonyanya kukosha pakuisa pa substrates dzakadai se zinc-alloy die-castings. Zinc-alloy die-castings inoshandiswa zvakanyanya mukugadzira zvinhu zvekushongedza, zippers, uye zvikamu zvidiki zvemakanika. Sezvo zinc-alloy ichikanganiswa nekuora mu acidic plating solutions, nzira yekuisa copper-based cyanide inowanzo shandiswa sedanho rekutanga kuisa plating. Copper layer inoiswa uchishandisa cyanide-ine electrolyte inodzivirira zinc-alloy substrate kubva munzvimbo ine acidic ye plating processes dzinotevera, dzakadai se nickel plating, uye inovandudzawo kunamira kwe nickel layer.

2. Kuisa Sirivha : Sodium cyanide inoshandiswawo mukuisa silver electroplating. Silver-cyanide complexes inoumbwa mu electrolyte, izvo zvinoita kuti sirivha igare yakatsetseka uye yakajeka. Zvinhu zvakaiswa sirivha zvinowanzo shandiswa muindasitiri yezvishongo, kugadzira midziyo yetafura, uye kubatana kwemagetsi. Kushandiswa kwe sodium cyanide mukuisa silver electroplating kunoita kuti ipedzise zvakanaka, ne sirivha ine reflectivity yakanaka uye inodzivirira ngura.

3. Kuisa Zinc Plating : Kunyange hazvo paine kuedza kwakaitwa kugadzira maitiro ekuisa zinc asina cyanide, mune dzimwe nguva, kuisa zinc electroplating kwakavakirwa pacyanide kuchiri kushandiswa. Macomplex e-zinc-cyanide akaumbwa nerubatsiro rwesodium cyanide anopa simba rakanaka rekukanda uye anobvumira kuiswa kwe zinc layer yakafanana. Kuisa zinc plating kunoshandiswa zvakanyanya kudzivirira ngura yesimbi nesimbi, senge mumaindasitiri ekuvaka nemotokari.

Kufunga Zvekuchengetedza

Pasinei nezvakawanda zvakanakira mu electroplating, sodium cyanide chinhu chine muchetura zvakanyanya. Inoburitsa hydrogen cyanide gasi kana yasangana nemaasidhi kana mvura. Naizvozvo, matanho akasimba ekuchengetedza anofanirwa kunge aripo munzvimbo dze electroplating dzinoshandisa sodium cyanide:

1. Kubata Nekuchengetera Zvakanaka : Sodium cyanide inofanira kuchengetwa munzvimbo yakachengeteka, ine mhepo inofefetera zvakanaka, kure neacids nehunyoro. Vashandi vanobata sodium cyanide vanofanira kudzidziswa maitiro ekubata nawo zvakanaka, kusanganisira kushandisa zvishandiso zvekudzivirira zvakaita semagurovhosi, magogorosi, uye dziviriro yekufema.

2. Zvirongwa Zvekupindura Panjodzi : Mafekitori emagetsi anofanira kunge aine zvirongwa zvakakwana zvekupindura panjodzi kana pakaita tsaona kana kuburitswa kwesodium cyanide. Zvirongwa izvi zvinofanira kusanganisira nzira dzekubuda munzvimbo iyi, kuderedza cyanide, uye kupa rubatsiro rwechiremba kuvashandi vakakanganiswa.

3. Kudzivirirwa Kwezvakatipoteredza : Mvura yakasviba inobva mumagetsi ine sodium cyanide inofanira kurapwa zvakanaka kuti ibvise cyanide isati yaburitswa munzvimbo yakapoteredza. Nzira dzekurapa dzingasanganisira makemikari anobvisa cyanide, ayo anoshandura cyanide kuita zvinhu zvisingakuvadzi zvakanyanya.

Mukupedzisa, sodium cyanide inoita basa rakakosha muindasitiri ye electroplating, ichigonesa kugadzirwa kwemhando yepamusoro, yakasimba, uye inoyevedza zvigadzirwa zvakapfava. Nekudaro, kushandiswa kwayo kunofanirwa kutarisirwa nekuchenjerera kuchengetedza kuchengetedzwa kwevashandi uye kuchengetedzwa kwezvakatipoteredza. Sezvo tekinoroji ichifambira mberi, kuyedza kuri kuitwa kugadzira mamwe maitiro, asina muchetura maitiro e electroplating, asi parizvino, sodium cyanide inoramba iri chinhu chakakosha mune akawanda electroplating application.
